requireApproval property not working for tools passed via toolsets parameter

import { createTool } from '@mastra/core/tools';
import { z } from 'zod';

// Create a tool that should require approval
const deleteUserTool = createTool({
  id: 'delete-user',
  description: 'Delete a user from the system',
  inputSchema: z.object({ userId: z.string() }),
  requireApproval: true, // ← This should require approval
  execute: async ({ userId }) => {
    console.log(`Deleting user ${userId}`);
    return { success: true };
  },
});

// Pass it via toolsets
const stream = await agent.stream('Delete user 123', {
  toolsets: { 
    admin: { 
      deleteUser: deleteUserTool 
    } 
  },
});
